HYDRCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 746,525, dated December 8, 19103.

I Application led November 21. 1902. Serial No.132.276. (No model.)

To @ZZ whom it may concern.-

Be it known that I, CHARLES H. KNoBBs, a citizen of the United States, residing at vElizabeth, in the county of Union and State of New Jersey, have invented a new and'Improved Hydrocarbon-Burner, of whichthe following is a specification.

My invention relates to hydrocarbon or oil burners for use in furnaces, and has for its object to provide a burner posessing new and advantageous features of construction and which is provided" with ready means of ad justment, so as to give in operation any eect desired.

In the accompanying drawings I have illustrated a form of burner embodying my invention.

Figure 1l shows the burner partly in section. Fig. 2 is a longitudinal sectional view, on a larger scale, of the feed end of the oil- Fig. 3 is a longitudinal sectional view of the delivery end of the oil-pipe.

Similar reference-numerals indicate corresponding parts in the different views of the J drawings.

1 represents the nozzle or vaporizing-chamber, fitted to the delivery end of an air lor steam supply pipe 2.V A suitable damper 3 is provided in the air or steam pipe to control the air or steam supply. The oil is led to the nozzle or Vaporizing-chamber from a suitable source of supply through pipes 4, 5, and 6. A valve 7,of suitable construction,is arranged in pipe 4. to regulate the supply of oil.

Pipes 5 and 6 are a continuation one of the other and form a continuous conduit for the oil. Iipe 6 has a sliding engagement with pipe 5, so that pipe 6 may be moved in or out with respect to the furnace.

In the form of my invention illustrated in the drawings the means employed to obtain the longitudinal sliding movement ofpipe 6 consists of a telescopic joint, the arrangement being as follows: To pipe 6. is coupled, by means of coupling 7, a tubular section 8,which surrounds pipe v5. In order to have oil-tight connection with pipe 5, pipe 6 is provided at its end with a stufting-boX 9, having the usual packing 10 and gland 11.

The means for adjusting the sliding movement of pipe`6 consists of a hand-Wheel 12,

having threaded engagement with said pipe. Hand-wheel 12 is mounted adjacent a bosson the air-delivery pipe 2 by means of a collarpiece 14, which engages an annular groove 15 on said hand-wheel and is secured in suitable position on the air-delivery pipe 2.

The engagement of hand-wheel l2 with pipe 6 may be directly With screw-threads or channels formed on said pipe, but is conveniently accomplished by providing a separate and veXteriorly-screwthreaded section 16, Isurrounding pipe 6 and threaded in the same coupling 7 which unites pipe 6 to slidable sleeve or section 8. (See Fig. 2.

It will readily be seen from the above description that by turning hand`wheel12 in one direction or the other the delivery end of the oilpipe may be extended into or Withdrawn from the furnace to any desired amount.

I provide the delivery end of the oil-pipe With means to insure the thorough and complete vaporization or atomizing of the oil. These means consist of spiral blades 23, mounted upon a cylindrical piece or sleeve 17, which surrounds the delivery end of the oil-pipe 6 and forms an annular space 18 between itself and the oil-pipe. Said sleeve 17 is shown connected with the threaded pipe 16 at 19.

The end of pipe 16 is expanded and slotted to form openings. (Indicated by the arrow 20, Fig. 1.) These openings are for the purpose of conducting air to the-space 18, su rrounding the end of the oil-pipe.

A suitable guide and supporting rail 2l is provided, having. one of its ends attached to the air-delivery chamber and its other end secured to the oil-pipe. A yoke-piece 22 is attached to the sleeve 8 and slides upon said supporting-rail 2].

The operation of the device wil-l be readily understood from the above description. The air-damper 3 and oil-valve 7 are opened to supply the proper amount ot' air and oil to produce the perfect vaporizing of the oil and to give the character of flame or jet desired.v By means of the adjustment obtained by the hand-Wheel 12 the jet or combustion of the oil may be directed and modified to give any effect desired. In the position shown in IOO Fig. l the delivery end of the oil-pipe is withdrawn within the vaporizing-chamber. This position gives a greater diffusion of the jet or flame, and consequently the spreading of the heat over aflarge area in the furnace. By screwing the delivery-pipe or burner out- Wardly toward the end of the nozzle or vaporlzing-chamber the burner is moved nearer the furnace, and the combustion or jetis more concentrated. It will thus be seen that any adjustment of the burner may be made to secure results varying from an intense flame or jet concentrated upon a particular point in the furnace to a widely-diffused combustion spreading over the whole furnace.

In addition to the adjustment of the jet to produce the variety of effects above described my invention permits the withdrawal of the burner end of the oil-pipe, together with the blades, from the furnace when the furnace is closed down. The burner is thus saved i from exposure to heat when not in operation.

This prolongs the life of the burner by preventing the burning away of its parts.

The construction of the burner with spiral Wings or vanes and the provision of means to conduct a portion of the air to the annular space surrounding the end of pipe 6 accomplish important results. The air passing around the outside of the burner and acted upon 'by the vanes tends to form a suction at the end of the oil-pipe. By conducting air within the sleeve on which the vanes are mounted this suction at the end of the pipe is destroyed.

Another important function served by conducting air to the annular space surrounding the end of the oil-pipe is the prevention of the deposition of carbon Within the pipe. In other forms of burners vthe oil-pipes have a tendency to clog or choke up due to the deposition of carbon from the oil therein, which results from the exposure of the pipes to the heat. My invention provides means whereby the end of the oil-pipe is kept cool and baking of the oil and deposition of carbon resulting in the choking of the pipes is prevented.

I have mentioned air as a vaporizing agent; but it will be understood that steam or any other suitable agent may be employed without departing from my invention.

By my invention it will be seen that I have provided a burner which permits of an easy adjustment throughout a Wide range, en abling the heat to be regulated and directed according to the nature of the work in hand. It also provides an' efficient means for securing a uniform vaporization of the oil, obviating the formation of any suction or vacuum zones in the blast, while at the same time preventing clogging of the pipes.

I-Iaving thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
